Does anyone notice slow battery charging while using the Galaxy S9?

JUMP TO SOLUTION

I got an S9+. However, if I'm charging my phone while using it, the battery charges really slow. On the notifications, it says it's fast charging, and gives an estimate amount. On the other hand, this app has a diagnostics tool. It will tell you how long it will take for the phone to fully charge, usually if I'm low on battery it would say around 3 hours. I'm not sure if this is a security feature implemented by Samsung to avoid overheating or what not. I did not see any warning, label, or anything stating that the battery would slow-charge while using it.

Samsung disabled fast charging while phone is being used back on the s7 or s8. This is known and was mentioned by CNET in 2017.

You know it's funny reading this I've been thinking exactly the same thing. I swapped between the wireless charger and plug in but ridiculously slow. Never had this issue with any other device.
